Golden Gate
After thwarting a notorious villain at an eco-summit in Paris, the City Spies are gearing up for their next mission. Operating out of a base in Scotland, this secret team of young agents working for the British Secret Intelligence Service’s MI6 division have honed their unique skills, such as sleight of hand, breaking and entering, observation, and explosives. All of these allow them to go places in the world of espionage where adults can’t.
Fourteen-year-old Sydney is a surfer and a rebel from Bondi Beach, Australia. She’s also a field ops specialist for the City Spies. Sydney is excited to learn that she’ll be going undercover on the marine research vessel the Sylvia Earle. But things don’t go exactly as planned, and while Sydney does find herself in the spotlight, it’s not in the way she was hoping.
Meanwhile, there’s been some new intel regarding a potential mole within the organization, offering the spies a lead that takes them to San Francisco, California. But as they investigate a spy who died at the Botanical Gardens, they discover that they are also being investigated. And soon, they’re caught up in an adventure filled with rogue missions and double agents!
James Ponti
James Ponti writes the kind of books that make young readers feel like they’re in on the secret—that the world is full of puzzles, hidden missions, and brilliant kids just waiting to take the lead. With his knack for weaving mystery, humor, and heart into every chapter, Ponti has carved out a special space in middle-grade fiction—one where intelligence is celebrated and friendship is just as powerful as bravery.
Long before he was writing about young spies and sleuths, Ponti was crafting stories behind the scenes of TV shows. A former screenwriter and producer, he developed his storytelling instincts in the world of children’s television, learning the rhythm of a good joke, the importance of pacing, and how to keep a young audience hooked. That training grounds his novels in a cinematic energy—quick-witted dialogue, cliffhangers in just the right places, and characters that feel like real kids, not just plot devices.
City Spies
There’s something thrilling about watching a team come together—not just any team, but one made up of kids from around the world, each with a secret past and a very particular set of skills. City Spies taps into that energy with precision, turning the idea of elite espionage on its head and handing the mission over to the most unlikely agents: teenagers.
City Spies consists of seven books and series is set to expand with the upcoming release of one more book. The current recommended reading order for the series is provided below.
